8 Counterpart User Manual
2.3 Enclosure Disassembly
The Counterpart indicator enclosure must be opened to connect cables for load cells, communications, and
digital inputs/outputs.
Before opening the unit, ensure the unit is turned off and the power cord is disconnected from the
power outlet. The power outlet must be located near the indicator to allow the operator to easily
disconnect power to the unit.
Ensure power to the indicator is disconnected, then place the indicator on an antistatic mat. Remove the four
screws holding the top plate to the enclosure body and set them aside. Gently lift the top plate away from the
enclosure and disconnect any cables and set it aside.
2.4 Making Power Connections
The power source used for the Counterpart must be properly grounded to an acceptable earth ground and the
outlet must be a grounded outlet. If the scale is remotely mounted, the platform must be separately grounded
from the chassis ground screw located on the bottom of the platform. Connect this screw with 18 gauge wire to
the same earth ground system as the AC power source. Failure to ground the base may cause static buildup that
could cause damage to the electronics and/or give incorrect weight readings.
2.5 Load Cell Wiring
On all complete units, the load cell has been wired to the CPU load cell terminal at the factory. Wire the cable to
the CPU board’s J1and J2 connector as shown in Table 2-1.
If using a 4-wire connection, set JP1 and JP2 to ON. If using a 6-wire connection, set JP1 and JP2 to OFF.
2.5.1 Dual Channel Units
For units that have dual channels, connect cable from the 14 pin connector to JP1 and JP2. If not using a dual
base, remove the JP2 connector. Trim back the wires and tape.
